As a recent returner and having only played in concert bands in my youth, I was wondering how bands get on with each other. I'm West Yorkshire based so there are a lot of geographically close bands. is there much player movement from one band to say a higher section band if someone wants to push themselves or to a lower or non contesting band if someone is looking to take it easier. does it ever cause ill feeling when a player switches bands? what is everyone else's experience?
